diaton tonometer provides high reliability of measuring results and makes it possible
to diagnose glaucoma on the early stage and appoint necessary treatment and medicines.
The unique methodology of intraocular pressure measuring through the eyelid
applied in the device provides new resources in ophthalmotonometry, simplicity and
safety of tests.
Transpalpebral "diaton" tonometer is effective and irreplaceable in various situations:
- screening examinations of the patients
- IOP control during selection of adequate medicines
- IOP measuring in the presence in a patient of chronical conjunctivitis, erosions, edema and cornea dimness
- IOP measuring in patients after corneal surgeries
- ophthalmotone day monitoring
- IOP measuring in immobilized patients and in children
- IOP measuring during contact correction (lenses are not taken out).
New diaton tonometer has a number of indisputable
advantages, making the IOP measuring process handy for the doctor and comfortable for
the patient.
